Cardiopulmonary Compromise, CPR and AED Use
- Identify the clinical signs, symptoms, and atypical presentations of cardiopulmonary compromise, chest pain, and syncope.
- Execute the proper sequence of adult cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) pad application according to established parameters.
- Demonstrate appropriate technician responses to life-threatening arrhythmias, artifact mimicry, and foreign body airway obstructions while maintaining the professional scope of practice.
The EKG Technician's Scope and Recognizing Cardiopulmonary Compromise
The primary responsibility of the EKG technician is to acquire diagnostic-quality tracings while continuously observing the patient for signs of physiological distress. Before beginning an EKG procedure, the technician must verify the patient's identity using at least two independent identifiers. Throughout the entire test, the technician maintains focus on patient safety, lead placement, and recognizing artifact. While technicians must recognize and promptly report concerning or potentially life-threatening rhythms to the healthcare team, clinical interpretation and medical diagnosis remain the sole responsibility of the provider.
Cardiopulmonary compromise occurs when there is impaired cardiac function, respiratory function, or both. This impairment results in inadequate tissue perfusion, oxygenation, or both throughout the body. Because physiological deterioration can occur rapidly during diagnostic testing, the technician must constantly monitor the patient for both objective signs, which are observable clinical findings, and subjective symptoms, which are issues reported directly by the patient.
Objective signs of cardiopulmonary compromise include cyanosis, diaphoresis, tachypnea, and hypotension. Cyanosis is a bluish discoloration of the lips, nail beds, or skin that can result from low blood oxygen levels or poor peripheral circulation. Diaphoresis is excessive sweating that may accompany acute coronary syndrome, shock, or other severe causes of distress. In contrast, subjective symptoms reported by the patient include severe shortness of breath, dizziness, palpitations, and chest discomfort. An everyday example of this distinction is seeing a patient break into a cold sweat and breathe rapidly (objective signs) while they describe feeling faint and experiencing a fluttering sensation in their chest (subjective symptoms).
| Clinical Category | Definition and Description | Specific Patient Presentations |
|---|---|---|
| Objective Signs | Directly observable or measurable physical indicators of inadequate tissue perfusion or oxygenation | Cyanosis (bluish lips, nail beds, skin), diaphoresis (excessive sweating), tachypnea, and hypotension |
| Subjective Symptoms | Physical sensations and distress experienced and reported directly by the patient | Severe shortness of breath, dizziness, palpitations, and chest discomfort |
Common mistakes
- Delaying chest compressions to detach EKG lead wires or remove electrode patches when a patient experiences sudden cardiac arrest.
- Performing a blind finger sweep inside an unresponsive choking patient's mouth, which risks pushing the foreign object deeper into the airway.
- Pausing to palpate a carotid pulse immediately after an AED delivers a defibrillation shock instead of instantly resuming chest compressions.
- Assuming an absence of classic substernal chest pain rules out a myocardial infarction in female, diabetic, or older adult patients experiencing atypical symptoms.
Key points
- EKG technicians continuously monitor for cardiopulmonary compromise, acquire diagnostic tracings, and immediately report emergent changes, while diagnosis remains the provider's responsibility.
- Cardiopulmonary compromise involves impaired cardiac or respiratory function leading to inadequate perfusion, oxygenation, or both, and may present with signs such as cyanosis and diaphoresis or symptoms such as dyspnea and chest discomfort.
- Myocardial infarction may present without typical chest discomfort, including with fatigue, nausea, or shortness of breath, particularly in older adults and people with diabetes; chest discomfort remains common in women, and diabetic neuropathy may contribute to reduced pain perception.
- High-quality adult CPR requires chest compressions at a rate of 100 to 120 per minute, a depth of 2 to 2.4 inches, complete chest recoil, minimized pauses under 10 seconds, and a 30:2 compression-to-ventilation ratio.
- AED pads are placed anterolateral (upper right chest and lower left chest), avoiding pacemaker bulges by at least one inch, removing transdermal patches from pad sites, and ensuring no contact during analysis and shock delivery.
- Ventricular fibrillation and pulseless ventricular tachycardia are shockable, while asystole and pulseless electrical activity are non-shockable; CPR must resume immediately after every shock without a pulse check.
- Severe airway obstruction in responsive adults is treated with alternating cycles of five back blows and five thrusts (abdominal, or chest thrusts if pregnant/unencirclable), transitioning directly to CPR if unresponsiveness occurs.
